The followings are the results of the study on industrial accidents occurred at 12 factories manufacturing metal products during the period of 2 years from January 1980 to December 1981 in the area of Yong-Dung-Po in Seoul. The results of the study are as follows: 1. The incidence rate of industrial injuries was 45.7 per 1, 000 workers, of the sample group and the rate of male (54.0) was three times higher than that of female ('17.5). 2. In age groups, the highest rate was observed in the group of under 19 years old with 83.5, awhile the lowest in the group of 40s. 3. It was found that those who had short term of work experience produced a higher rate of injuries, particularly, the group of workers with less than 1 year of experience showed the highest rate of it as 48.1%. 4. In working time, the highest incidence rate occurred 3 and 7 hours after the beginning of their working showing the rate of 6. 0 and 6. 1 per 1, 000 workers, respectively. 5. The highest incidence rate was observed on Monday as 8.4 per 1, 000 workers, and it was 18.3% in aspect of the days of a week. 6. in aspect of the months of a year, the highest incidence was observed on July as 5.4 per 1, 000 workers and the next was on March as 4. 8. These figures account for 11.8% and 10.5 of total occurrence in respective month. 7. In causes of injuries, the accident caused by power driver: machinery showed the highest rate with 37.5%, the second was due to handling without machinery with 17.2%, and the third was due to falling objects with 14.2%, and striking against objects with 10.2%, and so on. 8. By parts of the body affected, the mist injuries 84.3% of them occurred on both upper and lower extremities with the rate of 58.8% for the former and 25.5% for the latter. Fingers were most frequently injured with a rate of 40.3%. Comparing the sites of extremities affected, rate of injuries on the right side was 55.0% and 45.0% on the left sloe. 9. In the nature of injury, laceration and open wound were the highest w th 34.0%, the next was fracture and dislocation with 31.90, and sprain was the third with 8, 10. On the duration of treatment, it lasted less than one month in 68. 9~, of the injured cases, of which 14.5% of~the cases were recovered within 2 weeks, and 54.4% of them were treated more than 2 weeks. And the duration of the treatment tended to be prolot~ ged in larger industries. 11. The ratio of insured accidents to uninsured accidents was 1 to 4.7.

In order to clarify the contamination of vegetable gardens with human intestinal helminths, the soil samples were examined for the presence of eggs and larvae during the period from September 1973 to August l974. When soil samples collected from the vegetable gardens in Taegu were examined, four species of helminth eggs (ascarid, whipworm, hookworm and liver fluke) and a number of unknown eggs were found. Ascarid was found to be highest in the rate of detection(82.5 percent), followed by whipworm. The rates of hookworm, liver fuke and Trichostrongylus species were unexpectedly low. There was no difference between detection rate of vegetable gardens and that of vinyl green houses. However, the average number of helminth eggs detected from the soil of vinyl green houses was higher than the number of vegetable gardens. In the monthly incidence of ascarid eggs, the highest rate was found in September, and the least often was observed in August. While, the peak in the average number of the egg was encountered in August. There was no distinct trend in the monthly incidence of whipworm. However, it is likely that the detection number of whipworm per 100 gm of soil examined was relatively abundant in a period from May to August, and very little from October to April of next year. When the soil of vegetable gardens was divided into superficial, intermediate and deep layers and examined for presence of ascarid egg. The average number of the eggs found of the superficial layer was more abundant than those of the intermediate and deep layers, but the rate for the former was similar with the latter. In the demonstration of larval nematodes from the soil of vegetable gardens and vinyl houses, there found the filariform and rhabditoid larvae of hookworm and the larvae of Trichostrongylus species and unknown one. The majority of the larvae detected was belonged to unknown species, followed by hookworm larvae. The least was found in the rate of Trichostrongylus species. Generally, the filariform larva of hookwom could be detected during the hot season from May to August, but no larva was found in the winter. This suggests that the soil of vegetable gardens and vinyl green houses in Taegu is contaminated with human intestinal helminths.

This study was to find out whether there were differences in the levels of depressions between positive and negative schizophrenics. This research was derived from the fact that negative schizophrenics show higher levels of depression than positive schizophrenics. This study also examined the levels of psychomotor dysfunction in positive and negative schizophrenics. For this study, there were 453 subjects. They consisted of 119 positive schizophrenics, 122 negative schizophrenics and 212 normal people. They were asked to complete Zung's Self-Rating Depression Scale(SDS) and to perform one subtest, Digit Symbol of KWIS(Korean Wechsler Intelligence SCALE). Subjects levels of depression were measured by the SDS. The level of psychomotor dysfunction was measured by Digit Symbol subtest of Korean Wechsler Intelligence Scale. ANOVA and Duncan's multiple comparison analysis were used to examine whether there were differences of depression and psychomotor dysfunction among the normal people, positive and negative schizophrenics. The results were as follows ; It was found that the depression level was higher in the negative schizophrenic patients than positive schizophrenic patients. Levels of depression were significantly higher in negative schizophrenics than positive schizophrenics. Psychomotor retardation symptom was the most effective variable that discriminates between the normals and the schizophrenics. And it would be concluded that the psychomotor dysfunction was more severe in negative schizophrenics than positive schizophrenics.

The purpose of this study was to investigate the trait cortical arousal level, measured by extraversion-introversion, in schizophrenics. Subjects in this study were 231 (chronic schizophrenics= 78, acute schizophrenics= 62, and normal persons= 91). All subjects were asked to respond to extraversion-introversion subtest scale in the korean EPQ(Korean Version Eysenck Personality Questionnaire). Collected data were analyzed by using the. t-test and one-way analysis of variance. Results were as follows: 1) Trait cortical arousal level of chronic schizophrenics, which was measured by extraversion-introversion subtest scale in the Korean EPQ, was statistically higher than that. of. acute schizophrenics and normals. 2) Acute schizophrenics and normals were not significantly different in the trait cortical arousal level. However, the trait cortical arousal level of chronic schizophrenics was higher than that of acute schizophrenics. Therefore, it may state that the trait cortical arousal level of schizophrenics is getting higher when schizophrenic symptoms become more chronic.

BACKGROUND: Fatigue is one of the most common complaints of primary care practices and consists of symptoms of physical diseases and neurotic symptoms. This study was conducted to find that fatigue related to neurotic symptoms is as important as fatigue related to symptoms of the physical diseases itself. In addition to it, this study is to clarify and to understand the details of the neurotic symptoms. METHODS: In the course of six months(from April to september, 1996.), the 73 subjects were selected among the people that visited the outpatient department of family medicine with symptom of fatigue. The control group was selected from the healthy population which matched nearly the same number as the fatigue group. As tools of measurement, we used SCL-MPD consisted of 67 items. We performed statistical analysis among the data by means of SPSS/PC+. We analysed statistical dat,a for significance using non-parametric Mann-Whitney U test. RESULTS: There was no difference between the prevalence of men and women in the fatigue group. As the level of education decreased and employment increased, the proportion of patients that complained of fatigue increased. The fatigue group scored significantly higher than the control group in all questionnaire of SCL-MPD. The results of the somatization scale and phobic-anxiety were significant,ly high(p<0.01) and the rest of the scales were even more significantly high(p<0.001). Women scored higher in all aspects of SCL MPD than men. CONCLUSIONS: The author emphasize the importance of neurotic symptoms related to fatigue and biopsychosocial approach towards the patient. Considering the increase in medical cost and the decrease in productivity due to fatigue, there needs to be a thorough study on fatigue.

The purpose of this article was to determine the discriminant function analysis of the Korean Wechsler Intelligence Scale (KWIS) for 110 normal controls and 98 schizophrenics. Of special interest was to verify the clinical discriminant power of two subtests of the KWIS (Vocabulary and Digit Symbols) and Zung's Self-rating Anxiety Scale (SAS). Four major hypotheses were postulated. The normal control group would show higher scores then the schizophrenics; mean scores on both Vocabulary and Digit Symbol. The mean difference in Digit Symbol between the two groups would be greater than that in the Vocabulary. There would be no significant relation among Digit Symbol, Vocabulary, and Anxiety. The most powerful discriminant power would be expected from subtest of Digit Symbol. The mean discriminant scores were 1.34425 for the control subjects, 1.34425 for the schizophrenics. The correctly discriminated percentage was 89.1% for the control subjects, 90.8% for the schizophrenics. From the findings it was concluded that both Digit Symbol and Vocabulary scales had strong diagnostic value but the former was more powerful than the latter. However, the Anxiety scales had less diagnostic value.
